Choledochoscopy combined with double-cannula lavage in the treatment of acute pancreatitis with encapsulated necrosis and the analysis of related inflammatory indexes.

ABSTRACT

OBJECTIVE: This study aimed to evaluate the application of choledochoscopy combined with double-cannula lavage in the treatment of acute pancreatitis (AP) with encapsulated necrosis and analyzed related inflammatory indexes. METHODS: Thirty patients with AP with encapsulated necrosis were enrolled and treated with choledochoscopy and double-cannula lavage. Serum white blood cell (WBC), procalcitonin (PCT), C-reactive protein (CRP), interleukin 6 (IL-6), IL-8, tumor necrosis factor alpha (TNF-α), and related inflammatory indexes were detected before and after surgery. RESULTS: All of the participants who underwent the surgery recovered well and were discharged without serious complications; no deaths occurred. The serum WBC, PCT, and CRP of patients after surgery decreased compared with before the procedure, and the differences in WBC and CRP were statistically significant (P < 0.05); the difference in PCT was not statistically significant (P > 0.05). Postoperatively, IL-6, IL-8, and TNF-α levels were higher than before surgery, and the differences were statistically significant (P < 0.05). CONCLUSION: The surgical method presented herein effectively controlled and alleviated the infection of patients; it also did not increase the risk of infection and can thus be considered a safe and effective surgical method.
